HC0240.The horizontal coordinates were scaled from a topographic map and have
HC0240.an estimated accuracy of +/- 6 seconds.
HC0240
HC0240.The orthometric height was determined by differential leveling
HC0240.and adjusted by the National Geodetic Survey in June 1991.
HC0240
HC0240.The geoid height was determined by GEOID99.
HC0240
HC0240.The dynamic height is computed by dividing the NAVD 88
HC0240.geopotential number by the normal gravity value computed on the
HC0240.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
HC0240.degrees latitude (g = 980.6199 gals.).
HC0240
HC0240.The modeled gravity was interpolated from observed gravity values.
